I get the strong feeling that you are very new to this game. If thats the case you really should dip your feet in before you take the plunge ~ you'd be a heck of a lot better off starting at 1000 and working your way up.
As for the list, I'm tired as hell so I'm only going to go over two bits. Theres plenty more to talk about though
First up, those Nobs. What do you want these guys to do? If it's crack open tanks, they're fine, though you could probably save a bunch of points dropping the unneeded Big Choppas. If you want them to be able to bust open some
MEQ or
TEQ as well, you'll probably want 1-2 more
PK per unit to be honest. Either way the
BC are pretty much useless here unless your wanting to take Kombi Skorchas with them ~
BC are statistically about the same as a slugga and choppa, except against very tough targets. Against your run of the mill rank and file its not really any different except that it costs you more.
Secondly, I'm intrigued by one of your entries;
Troop 1 – Nob
(Eavy Armour/Bosspole/ Big Choppa/ Shoot-Scorcha)
10 Boyz
1 Burna Boy
Dedicated Trukk
(Red Paint Job/ Armour Plates/ Reinforced Ram/ Big Shoota/ Stikkbomb Chukka)
I'm pretty sure that the Shoota Skorcha is not available for Nob leaders, and the Burna certainly isn't an option.
That aside, Armour Plates are a huge waste of points, as is the stikkbomm chukka. The first upgrade is pretty bad all around, but worthless here, and the second upgrade is just plain worthless 100% of the time. For the 15 points your spending I'd say your getting perhaps 2 points worth of actual 'value' added to your army.
I'm not going to explain how exactly these upgrades are pretty poor. Instead, it would be a good exercise for a new player to try and figure that out for themselves. List building is half of this game (the other is rolling on various random tables and for first turn...), it's probably a good idea to get that down before you go throwing 2500 points worth of models at someone
Edit: Blah, beaten to the punch by *two* people. I've lost my touch
